A vaccine against the deadly Ebola virus has
led to 100 per cent protection and could transform
the way Ebola is tackled, preliminary results sug-
There were no proven drugs or vaccines against
the virus at the start of the largest outbreak of
Ebola in history, which began in Guinea in December
The World Health Organisation (WHO) said the
findings, being published in the Lancet, could be
Experts said the results were "remarkable."
This trial centred on the VSV-EBOV vaccine,
which was started by the Public Health Agency of
Canada and then developed by the pharmaceutical
It combined a fragment of the Ebola virus with
another safer virus in order to train the immune
system to beat Ebola.
A unique clinical trial took place in Guinea. When
a patient was discovered, their friends, neighbours
and family were vaccinated to create a "protective
ring" of immunity.
This could be the breakthrough the world has
been waiting for.
There is caution as the results are still preliminary,
with more data coming in. But officials at the WHO
believe the effectiveness of the vaccine will end
up being between 75 per cent and 100 per cent.
If such a vaccine was available 18 months ago
then thousands of lives could have been saved.
There are still other vaccines being trialled---
notably from GSK and Johnson&Johnson---although
as the number of cases continues to fall it is becom-
ing increasingly difficult to prove how effective
Ebola will inevitably come again. The hope now
is that the legacy of this unprecedented outbreak
will be a vaccine that means a tragedy of this scale
can never be repeated.
One hundred patients were identified in the trial
between April and July and then close contacts
were either vaccinated immediately, or three weeks
In the 2,014 close contacts who were vaccinated
immediately, there were no subsequent cases of
Ebola. In those vaccinated later, there were 16 cases,
according to the results published in the Lancet
The WHO says it is so far 100 per cent effective,
although that figure may change as more data is
Close contacts of Ebola patients in Guinea will
now be vaccinated immediately. And since the vac-
cine has been shown to be safe, that process will
also be extended to include children.
Médecins sans Frontières (MSF) is involved with
this research, and is part of a parallel trial for front-
line healthcare workers.
Medical director Bertrand Draguez said the Lancet
results should spur instant action.
"With such high efficacy, all affected countries
should immediately start and multiply ring vac-
cinations to break chains of transmission and vac-
cinate all frontline workers to protect them."
Marie-Paule Kieny, an assistant director general
at the WHO told BBC News: "It is certainly prom-
ising. We have seen that where rings have been
vaccinated, the transmission has stopped.
"Prior to vaccination there were cases, cases,
cases. The vaccine arrives and 10 days later the
cases are flat.
"It could be a game-changer because previously
there was nothing, despite the disease being iden-
tified 40 years ago.
"When there is a new outbreak this vaccine will
be put to use to stop the outbreak as soon as
possible to not have the terrible disaster we
More than 11,000 people have died from Ebola
and nearly 28,000 have been infected.
The sheer scale of the 2014-15 outbreak led to
an unprecedented push on vaccines---and a decade s
work has been condensed into around ten months.
The number of cases has fallen---and in the week
up to July 26th, 2015, there were just four cases
in Guinea and three in Sierra Leone.
Prof John Edmunds, from the London School of
Hygiene & Tropical Medicine, helped design the
trial: "The development has been at an absolutely
"This is very good news, these are very significant
results, the epidemic is not over and this shows
we have another potential weapon.
"The trial is still continuing, these are interim
results which need confirming, but there s now
light at the end of the tunnel."
Dr Jeremy Farrar, the director of the Wellcome
Trust medical charity, said this was a "remarkable
result" and was the product of international col-
He added: "Our hope is that this vaccine will
now help bring this epidemic to an end and be
available for the inevitable future Ebola epidemics."
